Question

Yasir is fifteen years elder than Mujtaba. Five years ago, Yasir was three times as old as Mujtaba. Then Yasir’s present age will be:

Answer 1

Yasir's present age is 27.5 years

Step-by-step explanation:

Let the present age of Mujtaba be x

We are given that Yasir is fifteen years elder than Mujtaba

So, Yasir's present age = x+15

Mujtaba's age 5 years ago = x-5

Yasir's age 5 years ago = x+15-5=x+10

Five years ago, Yasir was three times as old as Mujtaba.

x+10=3(x-5)

x+10=3x-15

25=2x

12.5 years =x

Yasir's present age = x+15=12.5+15=27.5 years

Hence  Yasir's present age is 27.5 years

Answer 2

$\underline {\blue { At \: present : }}$

Let the age of Yasir = x years,

Mujtaba's age = ( x + 15 ) years

$\underline {\blue { 5 \: years \:ago : }}$

Yasir's age = ( x - 5 ) years ,

Mujtaba's age = ( x + 15 -5) years

= ( x + 10 ) years

/* According to the problem given */

Five years ago, Yasir was three times as old as Mujtaba.

$x + 10 = 3( x - 5 )$

$\implies x + 10 = 3x - 15$

$\implies 10 + 15 = 3x - x$

$\implies 25 = 2x$

$\implies x = \frac{25}{2}$

$\implies x = 12\frac{1}{2} \:years$

$Yasir's \: present \:age (x) = 12\frac{1}{2} \:years$

Therefore.,

$\red {Yasir's \: present \:age (x)} \green {= 12\frac{1}{2} \:years}$
